control the volume of an audio output device.</p>
<p>The slider also displays an icon indicating if the volume of the
<a href="phonon-audiooutput.html">AudioOutput</a> it is connected
to is muted. The icon can be removed with <a href="phonon-volumeslider.html#muteVisible-prop">setMuteVisible</a>().</p>
<p>It is possible to set the <a href="phonon-volumeslider.html#maximumVolume-prop">maximum</a> value of
the slider. By default, the minimum and maximum values of the
slider are 0.0 (no sound) to 1.0 (the maximum volume the audio
output can produce).</p>
<p>Here follows a code example:</p>
<pre class="cpp">
     Phonon<span class="operator">.</span>AudioOutput <span class="operator">*</span>audioOutput <span class="operator">=</span> <span class="keyword">new</span> Phonon<span class="operator">.</span>AudioOutput(Phonon<span class="operator">.</span>MusicCategory);
     Phonon<span class="operator">.</span>createPath(mediaObject<span class="operator">,</span> audioOutput);

     volumeSlider<span class="operator">-</span><span class="operator">&gt;</span>setAudioOutput(audioOutput);
